Embodiment 1

[0025] Nusun oil (400 g) was placed in a 1 L round bottom flask and dried by heating the oil to 90° C. under vacuum for 30 minutes. Glycerol (80 g) and NaOH (1 g) were added to the dry oil with vigorous stirring. After reacting at 145° C. for 3 hours, the reaction mixture was cooled, and then the reaction mixture was centrifuged to separate the oil phase from residual glycerin for color measurement. The color of the oil phase was 12.5 red and 70 yellow. The initial Nusun oil colors were 0.8R and 4.1Y.

Embodiment 2

[0027] The same procedure as in Example 1 was adopted, except that the reaction time was 4 hours.

Embodiment 3

[0029] The same procedure as in Example 1 was used, except that the reaction time and temperature were 170° C. and 1 hour, respectively.

Abstract

A method for producing 1,3-diglyceride oils from triglyceride containing oils is disclosed. The method uses alkali metal salts or alkali earth metal salts of mono-carboxylic or di-carboxylic acids to drive glycerolysis under conditions such that commercial, food-quality 1,3-diglyceride oils are produced.

Description

technical field [0001] The present invention relates to a method for preparing 1,3-diglyceride oil from triglyceride-containing oil. More specifically, the present invention uses alkali metal salts or alkaline earth metal salts of monocarboxylic or dicarboxylic acids to drive alcoholysis of glycerol under certain conditions, thereby preparing commercial, food-grade 1,3-diglycerides. Background technique [0002] As obesity increases in industrialized countries, the incidence of degenerative diseases such as cardiovascular disease, hypertension and diabetes is also rising at alarming rates. Although obesity can be attributed to a combination of genetic, psychological, socioeconomic, and cultural factors, a more straightforward and conclusive explanation is that obesity is "caused" by an imbalance in energy intake compared to energy expenditure. As people gradually become more aware of the health crisis associated with obesity, more people are trying to live healthier lives, ...
